Testing the Conjugative Properties of Benzodithiophene
and Benzotrithiophene in Charge Transfer Multi(ferrocenyl) Systems
Posted on 2018-11-08 - 21:13
The
charge transfer properties of the mono-, di-, and tricationic
derivatives of bis(ferrocenyl)benzodithiophene and tris(ferrocenyl)benzotrithiophene
were investigated. The cations were generated by chemical oxidation
using ferrocenium(BF4) and acetylferrocenium(BF4) as the oxidative agents and monitored in the visible and NIR regions.
By changing the supporting electrolyte from [nBu4N][PF6] to [nBu4][B(C6F5)4], we were able to selectively generate
the monocationic species of bis- and triferrocenyl complexes. The
redox and optical properties of the cationic derivatives were rationalized
by an in-depth electrochemical and optical study. The comparison with
the results previously obtained for the structurally related bis(ferrocenyl)-s-indacene and tris(ferrocenyl)-trindene allowed for the
evaluation of the huge influence of thiolation on the metal–metal
electronic coupling.
